PRB: Server Object Error 'ASP 0178' Instantiating COM Object

• Active Server Pages
• Microsoft Visual Basic Learning, Professional, and Enterprise Editions for Windows, versions 5.0, 6.0
• Microsoft Visual C++, 32-bit Editions, versions 5.0, 6.0
• Microsoft Internet Information Server version 4.0

SYMPTOMS

When instantiating a COM component in an Out-Of-Process Server (EXE) from Active Server Pages (ASP), the following error may occur:

Server object error 'ASP 0178 : 80070005'
Server.CreateObject Access Error
testOOP.asp, line 12
The call to Server.CreateObject failed while checking permissions.
Access is denied to this object.

CAUSE

Appropriate permissions to access and launch the Out-Of-Process (OOP) COM object has not been set.

RESOLUTION

You need to give the IUSR_<machine_name> account permissions to launch and access your OOP COM object using dcomcnfg by doing the following:

1. Launch DCOMCNFG by clicking the Start button, selecting Run, and typing "Dcomcnfg" in the Run dialog box.



2. In the Default Security tab, click the "Edit Default" in the "Default Access Permissions" frame. The Registry Value Permissions dialog box appears.



3. Add the IUSR_<machine_name> account to the Registry Value Permissions dialog box, and click OK.



4. In the Default Security tab, click the Edit Default in the Default Launch Permissions frame. The Registry Value Permissions dialog box appears.



5. Add the IUSR_<machine_name> account to the Registry Value Permissions dialog box0, and click OK.

STATUS

This behavior is by design.
